c this routine tests the fortran assigned go to statement
c as described in section 11.3 (assigned go to statement). first a
c statement label is assigned to an integer variable in the assign
c statement. secondly a branch is made in an assigned go to
c statement using the integer variable as the branch controller
c in a list of possible statement numbers to be branched to.

c a compiler validation system for the fortran language
c based on specifications as defined in american national standard
c programming language fortran x3.9-1978, has been developed by the
c federal cobol compiler testing service. the fortran compiler
c validation system (fcvs) consists of audit routines, their related
c data, and an executive system. each audit routine is a fortran
c program, subprogram or function which includes tests of specific
c language elements and supporting procedures indicating the result
c of executing these tests.
c
c this particular program/subprogram/function contains features
c found only in the subset as defined in x3.9-1978.
